Pre-installation Tasks
This section describes the steps necessary to prepare a site for the installation of the Exalt Digital
Microwave Radio.
Link Engineering and Site Planning
Design all terrestrial wireless links prior to purchase and installation. Generally, professional wireless
engineering personnel are engaged to determine the viability and requirements for a well-engineered
link to meet the users’ needs for performance and reliability.
Exalt recommends using a link budget calculator and/or path planning tool to aid in the pre-planning
and engineering required to determine following attributes:
• Antenna type gain at each end of the link
• Antenna mounting height/location for proper path clearance
• Antenna polarization orientation
• RF cabling type, length, connectors, route, and mounting
• Antenna system grounding
• Lightning arrestor type(s), location(s), and grounding
• Radio mounting location and mechanisms
• Radio grounding
• Radio transmitter output power setting
• Anticipated received signal level (RSL) at each end
• Anticipated fade margin and availability performance at each end
• Radio settings
• Anticipated throughput performance
With respect to radio path and site planning, these radios are generally identical to other microwave
terrestrial wireless systems. Engineering of these systems requires specific knowledge about the
radios, including:
• RF specifications (transmitter output power, receiver threshold, occupied channel bandwidth, and
carrier-to-interference)
• Regulatory limitations on transmitter output power setting and antenna type/gain
• Noise/interference profile for the intended location
Familiarization with the ExtendAir eMIMO Series Radios
The ExtendAir eMIMO Series radios utilize time division duplex (TDD) radio transmission. This
means that the transmitted signal in both directions uses the same center frequency and transmits in
one direction for a period of time, and then in the opposite direction for another period of time. This
total period of time is referred to as the frame length or TDD frame length, and is further discussed in
Time Division Duplex (TDD) Factors
